Hello Josh,

I believe we’ve met before, I worked for Ewing late 90’s. Hope you are well!

The site is in San Francisco near city college. I’ve done some field work on the existing but just a little unsure about cast iron mains. If you could send me a couple names that would be great.

Thanks

Good point Marc. I have measured the psi at 80 but need to find someone to measure the flow.

Thanks!

Hi Susan,

I took A, B and D, last year and passed them all the first time.

I did use the Clarb tests and found them the most helpful of the self study materials. I would advise taking them early in your study, I took them the day before the test and had to do some last minute crunching.

The questions and answers are in the same format as the actual test, and some questions on the practice test were on the real test in my case. Also there is a self test mode on the practice exams. Here they will tell you the right answer and give you the reference book or periodical they are using for the test. (I spent a lot of time and money getting references and study materials.)

Since it is an online test once you’re done you have to pay another $60 to get online again. I believe it was timed but I don’t remember running out of time before I had extracted the info I needed.

Good Luck!

In California we have a guide put out by the California Dept. of Water Resources and UC Berkeley Cooperative Extension called “Water Use Classifications for Landscape Species (WUCOLS)”. It will give you water requirements for different plant species. You will have to adapt the California climate zones to your area though. If you google “wucols” it will give you download options in .pdf. The most current is wucols 2000 or wucols 3.

Good luck!

Hi Bianca,

The density factor “Kd” refers to how heavily the irrigated area is planted. The density can be at one or more horizontal levels depending on plant types. So the an area planted in tree’s, shrubs and groundcover will have a higher Kd factor (requiring more water) than an area planted in just groundcover.

For me this adds the 3rd dimension to the calculations.

I use the Weathermatic and Hunter controllers, specifying them as a designer and installing them as a contractor in residential situations. They are easy to use and reliable. They both use the onsite weather station which complies site data rather than reference data from weather stations miles away. They also do not require subscriptions or special online hook ups. Hunter has an wind option on theirs.

Important thing is to program the weather sensor correctly, so a programming note or spec. on proper settings may be included in the design plan package.
